UebiMiau inbox / receiving mail problems

I installed the UebiMiau.pkg for ispconfig and everything seemed to be working okay. My mailserver is postfix and it shows smtp and pop3 running. I setup the mail accounts for the site through ispconfig and set a forward address as well. When I send an email to the address [email protected] it forwards to the correct address but it does not show up in the inbox when I login to the mail client. I tried accessing my inbox with a regular email client and it accessed the inbox fine but it did not show that I had received any mail. When I tried to send mail through the client it would not connect through smtp. I checked the user's mail directory as well and there is no mail received. What am I missing here that's causing me to not be able to send or receive mail other than through a forwarded mail address for the created email accounts?

I created a new email to test so i could paste the log output, but the new address is working with no problems. Maybe because I enabled maildir after the accounts were created? I tried deleting one account and re-creating and it gives me an error saying "duplicate email address". Is there a way to re-create the email address again? Everything seems to be working now.
